BUTTONHOLE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 715,810, dated December 16, 1902.

Original application filed August 7, 1901, Serial No. 71,181. Divided and this application filed May 16, 1902. Serial Ila-107,610. (No model.)

To all whom it may concern:

Be it known that 1, AUGUST J EUDE, mechanician, residing at Okriftel, near Hattersheim-on-the-Main, in the German. Empire,

have invented new and useful Improvements in Buttonhole-Cutters, of which the following is a specification.

My invention relates to an improvement in the form of the knife which cuts the buttonro hole preliminary to sewing. These knives in buttonhole-cutters have usually an eye at one end to cut out a little piece of fabric to form the so-called eye of the buttonhole. The improvement relates to a special needle or I 5 hook arranged inside the eye of the knife and serving to remove securely the cut-out pieces of fabric.

The present application is a division of another application for patent filed by mein the United States Patent Office on August 7,1901, Serial No. 71,181, which application relates to improvements in buttonhole sewing machines, while the present case, as above mentioned, relates to a device for forming buttonholes and removing the pieces of fabric which are cut out in the formation of the buttonhole.

The invention will befully described hereinafter and the features of novelty pointed out in the appended claims.

In the accompanying drawings, Figure 1 is an elevation of one form of my improved buttonhole-cutter with parts in section. Fig. 2 is an end view with parts in section on line 2 2 of Fig. 1, and Fig. 3 isa bottom plan View.

a is the knife for cutting the buttonhole, and b is its eye.

0 is the needle, the end of which protrudes under the edge of the eye I) and is provided with a hook d. The needle is tapering and attached at its'broader upper end by an arm to the body of the knife a. At the point 6 there is a curved edge, preferably overhanging the eye I).

The action of the device is as follows: The 4 5 hook (1 will stitch into the fabric and raise the piece of fabric cut out by the eye b. These pieces will assemble on the needle and move up to the edge c. This will cut one side of every piece of fabric through, so that it falls off the needle.

It will be understood that the needle I) has a sharp lower edge at the bend e, as shown in Fig. 2, and that the pieces of fabric when out or slit by the said edge fall on the side away from the knife (1.

Now what I claim, and desire to secure by Letters Patent, is the following:

1. In a buttonhole-cutter the combination with an eyed knife of a hooked needle pro- 66 vided inside the eye of the knife.

2. In a buttonhole-cntter the combination with an eyed knife of a needle provided inside the eye of the knife and provided with a hook protruding downward under the edge of the knife.

3. In a buttonhole-cutter the combination with an eyed knife of a needle provided inside the eye of the knife and tapering down- Ward. 70

4. In a buttonhole-cutter the combination with an eyed knife of a needle provided inside the eye of the knife and with an arm carrying the needle at its upper end and having a cutting-shoulder at its bottom side, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

AUGUST J EUDE.
